FIGURE 19 is a perspective view of another container of this invention.I

Referring to the drawings in detail, a container 16 constructedaccording to this invention is shown in FIGURE 1. The container 16 ismade from a generally coplanar sheet or blank 18 shown in FIGURES 5 and6. The sheet or blank 18 is formed in a predetermined irregularconfiguration as illustrated. The sheet or blank 18 is made of anysuitable material, preferably, cardboard or paperboard or plastic or thelike.

The sheet or blank 18 has a rectangular side panel 20 and a rectangularside panel 22. Intermediate the rectangular side panels 20 and 22 is aside panel 24 which has edges 25 which converge. Thus, the side panel 24may be referred to as trapezoidal in shape. A side panel 26 hasconverging edges 27 and is also trapezoidal in shape. The rectangularside panel 22 is intermediate the trapezoidal side panels 24 and 26.Thus, one side edge 27 of the rectangular side panel 22 coincides with aside edge 27 of the trapezoidal side panel 26, and the other side edge25 of the rectangular side panel 22 coincides with a side edge 25 of thetrapezoidal side panel 24. The trapezoidal side panel 26 has an upperedge 21 and a lower edge 23, which are substantially parallel one withrespect to the other. The trapezoidal side panel 24 has an upper edge 28and a lower edge 29 which are substantially parallel one with the other.The trapezoidal side panels 24 and 26 are shown as having the samedimensions, but are inverted one with respect to the other.

The rectangular side panel 20 has lower and upper edges 33 which areequal in length and parallel one with the other. The rectangular sidepanel 22 has lower and upper edges 35 which are equal in length andparallel one with the other.

The rectangular side panel 20 has a flap 30 at one end thereof and aflap 32 at the other end thereof. The rectangular side panel 22 has afiap 34 at one end thereof and a flap 36 at the other end thereof.

The trapezoidal side panel 24 has a flap 38 at one end thereof and aflap 40 at the other end thereof. A fold line 42 is shown bisecting thetrapezoidal panel 24 and the flaps 38 and 40. The trapezoidal side panel26 has a flap 44 at one end thereof and a flap 46 at the other endthereof. A fold line 48 is shown bisecting the trapezoidal side panel 26and the flaps 44 and 46.

A flap 50 joins the flap 30, and a flap 52 is joined to the flap 50 andto the flap 38. A flap 54 is joined to the flap 38 and to a flap 56. Theflap 56 is also joined to the flap 36. A flap 58 is disposedintermediate the flap 36 and the flap 46. A flap 60 is also joined tothe flap 46.

An attachment strip 62 is joined to the flap 60. An attachment strip 64extends from one end of the attachment strip 62. The attachment strip 64is disposed along shown in the edge of the trapezoidal side panel 26. Anattachment strip 66 extends from the other end of the attachment strip64 and is joined to a flap 68 which is also joined to the flap 44.

A flap 70 is disposed intermediate the flap 44 and the flap 34 and isjoined thereto. A flap 72 is disposedintermediate the flap 34 and theflap 40 and is. joined thereto. A flap 74 is disposed intermediate theflap 40 and the flap 32 and is joined thereto.

Preferably, suitable fold lines are formed in the blank 18 by scoring orthe like along the edges of the side panels and between adjacent flapsand strips.

Any suitable adhesive material may be employed to secure portions of theblank 18 one to the other to form a container 16. Preferably,pressure-sensitive or temperature-sensitive adhesive material is appliedto the strips 62, 64, and 66 and to flaps 60, 58, 68, 7G, 72, and '74 ofthe surface of the blank 18 as illustrated in FIGURE 5. Such adhesivematerial is also applied to the surface of the flaps 58, 60, 72, 74, 70,and 68 of the blank 18 as shown in FIGURE 6. Adhesive material is alsoapplied, as shown in FIGURE 6, to a strip 80 at the edge of the flap 30and to a strip 81 at the edge of the flap 50 and to a strip 82 at theedge of the flap 52 and to a strip 83 at the edge of the flap 54 and toa strip 85 at the edge of the flap 34. It is to be understood, ofcourse, that adhesive material other than pressure-sensitive ortemperaturesensitive adhesive material or other attachment means may beemployed in regard to a container of this invention.

If desired, the blank 18 may be folded upon the fold lines 42 and 48.The surfaces of the strips 62, 64, and 66 to which adhesive material hasbeen applied, as shown in FIGURE 5, are then placed into engagement withthe right hand edge of the flaps 30 and 32 and the panel 20 forattachment thereto. Thus, the strips 62, 66, and 64 are secured to theedge of the flaps 30 and 32 and the panel 20, respectively. The blank 18then appears substantially as shown in FIGURE 7. If pressure-sensitiveadhesive material is employed, protective sheet material (not shown) isused to cover the other portions of the blank 18 to which thepressure-sensitive material has been applied to prevent adhesion withany other surface or element. In the form shown in FIGURE 7 the blank 18can be easily stored for future use. Also, in the form shown in FIGURE7, the blank 18 can be readily packed for shipping.

It is to be understood that the blank 18 does not need to be firstformed into the shape shown in FIGURE 7 in order to form a container. Ifthe step shown in FIG- URE 7 is eliminated, the fold lines 42 and 48 donot appear in the blank 18 as it is shown in FIGURES and 6.

The next step in forming the blank 18 into a container 16 is that ofopening the blank 18 to substantially the form thereof shown in FIGURE8. Any protective sheet material employed to cover the adhesive materialis removed therefrom.

As shown in FIGURE 9, the bottom of the container 16 is formed byfolding the flaps 68 and 70 to cover the flap 44 as the flaps 68 and 70are adhesively attached to the flap 44 by applying pressure thereto. Theopposite surface of the flap 70 is adhesively attached to the flap 34 asthe flap 34 is folded over the flap 70. The flaps 72 and 74 are foldedinto engagement with the flap 40 for adhesive attachment of one surfaceof each of the flaps 72 and 74 to the flap 40. The opposite surface ofthe flap 72 is attached to the flap 34. The flap 74 has the oppositesurface thereof attached to the flap 32. Then, the strip 85 of the flap34 is moved into position to cover a part of the flap 32 as the strip 85is adhesively attached thereto.

As shown in FIGURE 10, the top part of the container 16 is formed byfolding the flaps 58 and 60 into engagement with the flap 46 so that onesurface of each of the flaps 58 and 60 is attached to the flap 46. Theopposite surface of the flap 58 is attached to the flap 36 as the flap36 folds over the fiap 58. The opposite surface of the flap 60 isattached to the flap 30 as the flap 30 folds over the flap 60. Then, theflaps 52 and 54 are folded to cover the flap 38. The adhesive strip 82upon the flap 52 shown in FIGURE 6 is attached to the fiap 50, and theadhesive strip 83 upon the flap 54 shown in FIGURE 6 is attached to theflap 56. Following this, the strip of the fiap 30 and the strip 81 ofthe flap 50 are moved into position to cover a part of the flap 36 andto cover a part of the flap 56, as illustrated in FIGURE 10, as thestrips 80 and 81 are adhesively attached thereto.

Thus, the container of FIGURE 1 is formed. It is to be noted that as thecontainer 16 is formed, the upper edges 21, 35, 28, and 330i the sidepanels 26, 22, 24, and 20, respectively, become substantially coplanarand the bottom edges 23, 35, 29, and 33 of the side panels 26, 22, 24,and 20, respectively, become substantially coplanar. Thus, the bottomand top surfaces of the container 16 formed by the various flaps aresubstantially fiat and parallel. Thus, the container 16 has asubstantially flat cover at the top thereof and a substantially flatbase at the bottom thereof.

Either the bottom part of the container 16 or the top part thereof maybe formed first. The container 16 may be filled through either the topor the bottom thereof when that part of the container 16 is disposedupwardly.

The container 16 is adapted to contain a liquid or a powder material, ora granular material, or the like.

As illustrated in FIGURE 3, the flaps 52, 54, 38, 50, and 56 are adaptedto form a pouring spout. The pouring spout is formed as follows: Theflaps 52 and 54 are lifted away from the flap 38, thus separating thestrip 81 from adhesive attachment with the flap 56. Then, the flaps 52and 54 are separated from adhesive attachment with the flaps 50 and 56,respectively. Then, the flap 38 is pulled forwardly and formation of thepouring spout is completed. In order to permit such formation of thespout after assembly of the container 16, adhesive attachment of theflaps 52 and 54 to the flap 38 is to a rather limited degree.

It is to be noted that in the formation of the container 16 shown inFIGURE 1, the panels 20, 24, 22, and 26 shown in FIGURES 5 and 6 formthe side walls of the container 16. The surfaces of the side panels 20,24, 22, and 26 shown in FIGURE 5 become the exterior surfaces thereof.As shown and discussed, the panels 20 and 22 are rectangular in shape.Thus, the upper edge 35 of the panel 22 is equal in length to the bottomedge 35 thereof and the upper edge 33 of the side panel 20 is equal inlength to the bottom edge 33 thereof. The panels 24 and 26 have sideedges 25 and 27, respectively, which converge. The side edges 25 of thepanel 24 converge to ward the upper part of the container 16 and theside edges 27 of the panel 26 converge toward the bottom part of thecontainer 16. Thus, the upper edge 21 of the side panel 26 is longer inlength than the bottom edge 23 thereof and the uper edge 28 of the panel24 is shorter in length than the lower edge 29 thereof.

Also, as stated above, the bottom and top surfaces of the container 16are substantially flat and parallel. Therefore, when the blank 18 isformed into the container 16, there is relative lateral angular movementbetween the upper edge 35 of the side panel 22 and the bottom edge 35thereof, so that the upper edge 35 and the bottom edge 35 of the panel22 become disposed in different planes. Also, in like manner, the upperedge 33 of the side panel 20 and the bottom edge 33 thereof becomedisposed in different planes. Thus, the rectangular panels 20 and 22each assume a curved shape. FIGURES 1, 3, 4 and 8 show the rectangularside panels 20 and 22 curved inwardly. FIGURES l2 and 13 show the rectangular side panels 20 and 22 curved outwardly. Because of the outwardcurvature of the side panels 20 and 22, rather than an inward curvaturethereof, the volumetric capacity of the container 16 of FIGURE 12 may besome what greater than the volumetric capacity of the container 16 ofFIGURE 1.

Such curvature of the panels or side walls 20 and 22 provides strengthto the container 16 Which would not otherwise be possible. The container16 is capable of resisting appreciable internal or external pressures orforces without distortion or collapse thereof.

Due to the fact that the upper and lower surfaces of the container 16are substantially fiat and parallel, and due to the fact that acontainer 16 is capable of resisting appreciable external forces, aplurality of containers 16 can be stacked one upon another, asillustrated in FIG- URE 2. Even though a plurality of containers 16 arefilled with material, the containers 16 can be stacked in a plurality oflayers.

Furthermore, the concave side panels 20 and 22 of the container 16 ofFIGURE 1 provide recesses which facilitate manual grasping of acontainer 16 during pouring therefrom, as illustrated in FIGURE 3, orfor any handling of the container 16. When the container 16 is disposedat an angle for pouring therefrom, as illustrated in FIG- URE 3, thecenter of gravity of the container 16-, including the contents thereof,shifts to a lesser degree toward the pouring spout than occurs inpouring from a conventional type of container which is substantially aparallelepiped. This is due to the fact that most of the material Withinthe container 16 rests upon the trapezoidal side panel 24 of thecontainer 16 which is lowermost during pouring therefrom as illustratedin FIGURE 3. The trapezoidal side panel 24 has a smaller portionadjacent the pouring spout than the portion thereof spaced from thepouring spout. Therefore, while material is being poured from thecontainer 16, the material moves into a part of the container 16adjacent the pouring spout which is smaller in volume than a part of thecontainer 16 which is farther from the pouring spout. Thus, the centerof gravity of the container 16 and the material therein does not shiftgreatly toward the pouring spout during pouring of the material.Therefore, the container 16 is readily handled and controlled duringpouring therefrom.

It is to be understood that a container of this invention can beproduced in any one of various shapes and configurations. The shape ofthe container of this invention depends upon the relative dimensions ofthe opposed side panels, such as the panels 20 and 22, and the relativedimensionsof the opposed side panels, such as the panels 2.4 and 26, inwhich the edges converge or diverge. The shape of a container of thisinvention also depends upon the shape of the side edges of the sidepanels of the container.

FIGURE 14 shows a blank 106 for construction of another container ofthis invention. The blank 106 has opposed side panels 108 and 109, whichare similar in shape. The side panel 108 has side edges 110 whichgenerally converge upwardly so that an upper edge 112 of the side panel108 is shorter in length than a bottom edge 114 thereof. The side panel109 has side edges 110 which generally converge downwardly so that anuper edge 114 of the side panel 109 is longer in length than a bottomedge 112 thereof.

The blank 106 also has opposed side panels 118 and 119. Each of the sidepanels 118 and 119 has curved side edges. The side panel 119 has a sideedge 110 which coincides with a side edge 110 of the side panel 109. Theside panel 119 also has a side edge 110 which coincides with a side edge110 of the side panel 108. The side panel 118 has a side edge 110 whichcoincides with one of the side edges 110 of the side panel 108. The sidepanel 118 also has a side edge 120. Each of the side panels 118 and 119has an upper edge 122 which is equal in length to a bottom edge 124thereof.

The blank 106 is shown as having suitable upper flaps a FIGURES 5 and 6.A strip 129 extends along the side panel 109 for attachment to the sidepanel 118.

The blank 106 of FIGURE 14 may be formed into a container shown inFIGURE 15. The opposed side panels 118 and 119 of the container 130curve inwardly while the opposed side panels 108 and 109 curveoutwardly, as shown in FIGURE 15. However, one or both of the opposedside panels 118 and 119 may curve outwardly, rather than inwardly.

FIGURES 16 and 17 show a container which is formed from a blank 142shown in FIGURE 18. The blank 142 has opposed side panels 144, each ofwhich has opposed side edges 146 which curve one toward the other. Theblank 142 also has opposed side panels 147, each of which has the mutualside edges 146 of the side panels 144. However, the opposed side edges146 of the panels 147 curve one away from the other. Each of the sidepanels 144 has an upper edge 148 which is equal in length to a bottomedge 148. One of the side panels 147 has an upper edge 150- which isshorter in length than its bottom edge 152. The other side panel 147 hasan upper edge 152 which is longer in length than its bottom edge 150.The opposed side edges 146 of one of the panels 147 converge upwardlyand the opposed side edges of the other side panel 147 convergedownwardly.

Suitable flaps are integrally arranged at the top and bottom of the sidepanels'144 and 147. FIGURE 19 shows a container of this invention. Thecontainer 190 has two opposed rectangular side panels 192 and twoopposed side panels 194 which have converging edges 196. The convergingedges 196 converge to a point 198. The side panels 192 are shown curvedinwardly, but may curve outwardly.

The container 190 has a topcover 200- and a base 202. A pouring spout oraperture 204 is shown in the cover 200 for use if desired.

It is to be understood that a container of this invention is capable ofwithstanding relatively high external and/or internal pressures andforces without distortion or collapse. Furthermore, a container of thisinvention which has side portions which curve inwardly may be easily andreadily manually grasped for handling thereof.

Although the preferred embodiment of the device has been described, itwill be understood that within the purview of this invention variouschanges may be made in the form, details, proportion and arrangement ofparts, the combination thereof and mode of operation, which generallystated consist in a device capable of carrying out the objects setforth, as disclosed and defined in the appended claims.
